CLOSURE FOR ICE BAGS OR THE LIKE.

Application filed November 9, 1921. Serial No. 514,051.

improvements therein.

Such bags are usually formed with a large mouth in order to facilitate the introduction and removal of the cracked ice. They hence necessarily require a closure of considerable dimensions.

In the preferred construction of my invention, I provide a large nipple or socket member which is formed with screw-threads on its exterior and which is attached to the bag by vulcanization or otherwise. I also preferably provide a cap which has a downwardly projecting flange adapted to screw over the exterior threads of the socket member.

My invention in its preferred form also provides an interior rubber gasket which is vulcanized on the interior of the cap; preferably also the invention comprises a covering of rubber vulcanized to the exterior of the cap. Such covering avoids the excessive cold of a metallic cap, and also forms a gripping surface which is securely fixed to the cap, so that the cap may be easily manipulated in screwing and unscrewing it upon the socket member. According to the preferred form of the invention the rubber gasket in addition to being vulcanized on the cap itself is connected to the rubber covering so that it holds its position with double security. Preferably the two are connected through an opening in the metallic cap, and preferably also the rubber covering and gasket are integrally formed in a single vulcanizing operation.

Referring to the drawings, which illustrate several forms of the invention,-

Figure l is a diametrical section of an ice bag, showing the stopper and socket member in similar section.

Fig. 2 is an elevation of Fig. 1.

Fig. 3 is a plan of Fig. 1.

Fig. a is a diametrical section of a modification.

Fig. 5 is a diametrical section of'another modification.

Referring to the drawings, let A indicate the body of the ice bag which is usually formed with rubber, and B a metal or other socket member or nipple having a screw-' threaded exterior C and a bottom flange D,

by means of which flange the socket memher is attached to the body portion A.

E indicates the cap as a whole which has a flange F screw-threaded on itsinterior..

to engage the thread C of the socket member. G is a packing underlying the top wall H of the cap, against which wall the packing is pressed by the topof the nipple B when the'cap is screwed home.

According to the present invention the packing G is held in place by a portion which overlies the top wall H. In the preferred construction the top wall is provided with a large aperture, so that the wall in effect amounts to no more than a deep flange. The rubber is carried up through the opening, and has a portion I which overlies the top of the flange. The gasket portion is hence as it were clinched or riveted in place,

so that it cannot escape. Preferably the gasket G is vulcanized to the metal of the cap, so that it is irremovable except by destroying it. So also the portion I is preferably also vulcanized to the flange H. In lieu of the central opening a series of smaller openings K may be provided in the top of the cap, through which connection can be made between the washer portion and the overlying or top portion, shown in Fig. 4.

In the preferred construction I prefer to entirely cover the exterior of the cap with rubber, moulding the latter dowmvardly on the outer sides of the flange F of the cap, as shown at J. By this means a non-conducting or poorly conducting layer is provided on the outer sideof the cap, so that the user is protected from direct contact with the cold metal. It is an important feature of the invention that the portion J IOU shall be vulcanized directly to the cap, so I as to hold it firmly in place. and so as 1 to provide a gripping portion, by means of which the cap can be screwed and unscrewed, while at the same time avoiding any slippage between the metal and the rubber.

The preferred method of forming the cap and the inside gasket directly upon the cap in one operation, the rubber flowing into the interior of the cap and around the under side of the flange H, This method, however, is not claimed in the present application, since it forms the subject matter of another application filed by me.

Fig. 5 illustrates a construction in which the covering is omitted, the flange L overlying the top wall, as shown, and the packing and flange being preferably vulcanized in place upon the metal.

vulcanization is best carried to the point Where there is rigidity of connection between the metal and the rubber, and the rubber of about the hardness necessary to produce a proper packin While I have shown anc described several forms of the invention, it Will be understood that I do not Wish to be; limited thereto, since -various changes may be made therein Witlo-nt "departing from the spiritoi the intention.

What I claim is 1. A cap having a compressible packing on the under side of its top portion, said pine-king having a part extending through and overhanging the cap.

A cap having a compressible packing resting against the cap body and the cap body being perforated, the material of the packing e-xtei'iding through the perforation and overlying the opposite side of such cap.

3. A cap having "a wall, a compressible packing ono-ne side of said Wall, an aperture through said wall, the packing eXtendi-ng through the aperture, and overlying the wall on the opposite side.

4. A cap having a top portion, a depending flange, a compressible packing on the under side of said top portion, an aperture in said top portion through which the packing extends, and said packing having pertime overlying said top Wall.

A cap for ice bags '01 the like having =21 stiff body portion and a coating of nonheat-conducting material enclosing the exterior of said cap, said coating being strongly adherent to the 6. A cap for ice bags or ii-lie like hava stifl body portion provided with :1 perforation at its top, a co e 'ng of rnbber enclosing the exterior of said body portion, and a packing Within the cap, said com-ting I i and packing being connected through said perforation in the cap. 7 i

In Witness whereof, I have hereunto signed my name. 1
